Lubuntu won't detect my wifi or my ethernet when plugged in via cable.

I just installed 32 bit Lubuntu, and it wouldn't detect my wifi or ethernet. Anybody know what I need to do to get it working?

I know for sure that my wifi is working because I have another laptop connected to it. When I click on the network connections, and click on the button to add a network, it asks me for all this information I don't know about my network. Shouldn't it be able to detect that it is there?

The output of the command lspci run in a terminal should include information about your wired and wireless chipsets. Please post that output here, being sure to surround it with "Code" tags which become available when you click the "Go Advanced" button at the bottom of the "compose post" window.

For example (this is from a computer without a wireless card):

Code:

# lspci

(snip)

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c)

With certain wireless chipsets, most common Broadcom and Realtek, it's not uncommon to have to take a few extra steps to get them working. It is very unusual for Linux not to detect a wired connection. Have you tried connecting an ethernet cable to the computer?

Also, which release version of Lubuntu are you using?

Hello and welcome to LQ.

This may be a start too. https://help.ubuntu.com/community/Lu...tup#Networking

Although linux like one based on ubuntu has a lot of drivers there may be one of a few issues. One is user permission. Two is your driver can't be or isn't provided in the distro. Three is a wrong driver is being used. Many more but I'd think those are the big three.

Hi...

Welcome to the forum

In line with what frankbell has mentioned about the "lspci" command, a variant which will reduce the size of the output is this...

Code:

lspci -nnk | grep -i net -A2

Also, please post the results of these commands, as well...

Code:

iwconfig

Code:

ifconfig -a

Code:

rfkill list

Simply save these results to a text file using a USB drive, then transfer them over to a computer that has an internet connection.

Last but not least, what is the brand and model and model (and model number) of your computer?

Regards...
